Title: Power distributor
Inventor: BABA SADAAKI
IPC: H02J3/00
Filed: 1978-05-29
Abstract: PURPOSE: To make the promotion of miniaturization with a less requirement of the number of limiters, by means of such arrangement that, with a current limiter intermediately installed to lines of two phases of the three-phase lines, the connection of a short-circuit line be provided in the remaining phase.  
     CONSTITUTION: Into lines of two phases of the three-phase output lines of a main breaker 1, is intermediately inserted a current limiter 4, for presenting a non-linear impedance characterostic where the impedance rapidly increases when a conduction current increases, and in the remaining one phase is provided the connection of a short-circuit line 7. When caused a short-circuit fault in the secondary side of a branch breaker 3, the fault current flows in the branch breaker 3 through the main breaker 1, the current limiter 4 and the short-circuit line 7. With the fault current exceeding a level determined by the limiter 4, a rapid increase is caused in the resistance value of said limiter that suppresses the increase of the fault current. At this time, the branch breaker 3 is to disconnect the fault current making the fault circuit isolated. In such constitution, a requirement of only two current limiters, good enough for the three-phase use, can promote a miniaturization as compared with the method in which three current limiters have been usually required.

Filed: 1980-05-16
Abstract: PURPOSE:To simplify and make sure the demodulation, by combining a leading detection circuit with a counter and a D type FF circuit, and making demodulation through the discrimination of the period of FSK signal. CONSTITUTION:An FSK signal is converted into a rectangular wave at a waveform forming circuit 12, the leading of this signal is detected at a detection circuit 13, and detected pulses are given to a reset input of a counter circuit 15 and a clock input of a D type FF circuit 16. The counter circuit 15 is reset with the pulse from the circuit 13 and starts counting with the clock of an oscillation circuit 14 for counting. The counter 15 outputs the output having the period corresponding to the higher frequency fH of the FSK signal and the output having the period longer corresponding to a lower frequency fL. The FF circuit 16 takes the output of the counter 15 as the data input, and outputs an output 17 changed corresponding to fH or fL by taking the reset pulse as the clock, allowing to make demodulation of the FSK signal.

Filed: 1981-04-28
Abstract: PURPOSE:To reduce the access time, by providing a circuit element which keeps non-selection bit lines at a low level for a clamp circuit, so that a current flowing from the non-selection bit lines of a bipolar semiconductor memory to a discharge circuit through a memory cell cannot be caused. CONSTITUTION:A memory cell M11 consists of a flip-flop circuit in which PNP transistors (TR) Qa and Qb are taken as load and NPN multi-emitter TRs Qc and Qd are taken as detector and storage TRs, and is connected to word lines W, Wh and bit lines B0, B1. When the bit lines are not selected, they are pulled up to H level with a clamp circuit and this level is higher than the potential of the negative side word line Wh. Thus, current as shown in the dotted arrow lines flow, and one cell's share, (IH+ID)/n of currents flowing from constant current sources IH and ID is supplied with the current shown in dotted lines. Thus, the discharge current to lower the potential of the word lines and cells is reduced by this share, allowing to give a delay in the reduction of potential. Thus, the fall of the word lines can quickly be made and the access time can be decreased.

Title: Device for driving feed of transfer press
Inventor: IURA TAKAO
IPC: B21D43/05
Filed: 1988-03-18
Abstract: PURPOSE:To drive the feed of a transfer press by a small torque and to make the operation at higher speed by synchronously driving both arms by the respective cam by linking a feeding arm and return arm by a return link. CONSTITUTION:When a feed cam 33 and return cam 37 are integrally driven, a feed arm 32 is first rocked centering around a supporting shaft 31 along the feeding face of the feed cam and the feeding operation is performed by a cross bar by driving a feed bar 28. At this time, a return arm 36 is rocked in parallel to the feed bar 28 by a return link 38 and rocked in parallel to the feed arm 32 along the harmonic face of the return cam 37 itself as well. When the rotations of both cams progress the 180 deg. phase it is rocked by the reverse operation relatively to the feed operation onto the cross bar centering around the supporting shaft 35 and a return operation is performed by the cross bar. The feed of a transfer press is thus driven by a small torque and the operation can be made at higher speed.

Filed: 1980-05-16
Abstract: PURPOSE:To enable the polarized electromagnet to absorb an armature with small electric power by a method wherein magnetic flux of a supplementary permanent magnet is made to cooperate with magnet flux of a coil to act on the armature. CONSTITUTION:When no current is flowing in the coil 3, magnetic flux of a permanent magnet 4 for reversion flows as the armature 2-the center leg part 12-the side pole part 11, and the armature 2 is absorbed by a magnet 4. When a current is made to flow in the coil 3 to generate magnetic flux in the direction shown with an arrow mark, because the direction thereof is opposite from magnetic flux of the magnet 4, the direction is opposite from the direction of magnetic flux in the armature 2, and one end of the armature 2 and the magnet 4 make repelling condition. Moreover magnetic flux of the supplementary permanent magnet 5 flowing the middle leg part 12 joins with magnetic flux of the coil 3 to flow in the armature 2, and another end of the armature 2 makes the condition being absrobed to the tip side of a side leg part 13. When the current in the coil 3 is stopped, because force to absorb the armature 2 to the side leg part 13 is generated only by magnetic flux of the magnet 5, absorbing force generated by the magnet 4 overcomes this force to return to the first condition.
